sir, it may not be an offence under the state laws but it could be termed as moral turpitude under the code of conduct, if prescribed, of the MNC

in a private company, it is not mandatory to disclose that you an accused in a criminal case. however, if you disclose, you may not get the job. so u may do what is good for you but better do the job honestly.

no problem

Disclosing about the criminal case(s) are not mandatory. So relax .
